Several national and prominent Massachusetts Democrats, including Kerry himself, threw their support behind Markey last week.
Brown is considered a top GOP contender for the seat. He has dropped hints that he's interested in a run, but hasn't yet made it official.
His comments on the show previewed what could be a possible attack against Markey — questions concerning his residency in Massachusetts.
Markey claims his voting residency in his hometown of Malden, Mass. But he also owns a home in Chevy Chase, Md., and his wife works just outside of D.C.
Questions concerning Markey's residency have been a problem for him in the past. In 2010, his Republican opponent questioned where Markey truly called home, prompting Markey to produce government documents to prove he still has roots in Massachusetts.
A recent poll conducted for the congressman also asked respondents questions concerning his residency, to gauge their potential impact on his candidacy.
Brown was elected to the Senate in 2010 in a special election following the death of longtime Massachusetts Sen. Edward Kennedy.
